Re: [Nouveau] [RFC] Explicit synchronization for Nouveau

Versioning off tags for individual buffers then moves to working set modification time. This is more feasible if the only thing that needs precise fencing of individual surfaces is lifetime management. Yeah, there's always ways to make the fence assignment and tracking a bit more efficient, we're playing around with working-set tricks for i915 ourselves. But fundamentally you still have fences for each buffer object (just can't directly access them). And for buffers exported with dma_buf you still need the direct link I think, at least when you care about implicit syncing somewhat. The trend seems to be towards establishing a relatively large working set up front and then submitting many command buffers against it, perhaps with incremental modifications to the working set along the way. This may be what's referred to as the Android model above, but I view it as the non-glitchy graphic model going forward. Nah, that's something different. Afaik Android drivers don't really bother a lot with swap and page migration and having a working shrinker for gpu objects. At least our android guys need to disable the lowmemory killer since that thing just goes bananas if we driver i915 memory usuage against the wall and into swap. I'm not really sure what you mean by non-glitchy graphics, for me this can mean anything from avoiding stalls to proper syncing with vblanks to anything else really ... So might be good to elaborate here. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

[Nouveau] [Bug 84515] New: [NV96] HDMI audio works, but has audio gaps or pauses
https://bugs.freedesktop.org/show_bug.cgi?id=84515 Priority: medium Bug ID: 84515 Assignee: nouveau@lists.freedesktop.org Summary: [NV96] HDMI audio works, but has audio gaps or pauses QA Contact: xorg-t...@lists.x.org Severity: normal Classification: Unclassified OS: Linux (All) Reporter: ppaala...@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: unspecified Component: Driver/nouveau Product: xorg Created attachment 107133 -- https://bugs.freedesktop.org/attachment.cgi?id=107133action=edit output of lspci -nn I'm running 3.16.3-gentoo kernel with a nouveau [ DEVICE][:01:00.0] BOOT0 : 0x096500a1 nouveau [ DEVICE][:01:00.0] Chipset: G96 (NV96) On a whim, I decided to try HDMI audio. I plugged in the TV, and extended my desktop there. To my surprise, 'alsamixer' reports Card: HDA Intel and Chip: Nvidia MCP77/78 HDMI. In audacious' ALSA settings, I found a PCM device hw:0,3 labeled as HDMI 0. When I choose that as the output and play a song: - The laptop internal speakers, i.e. the whole normal analog audio output system, produces a loud static, which I have to mute in Alsamixer by muting Speaker. - The song comes out mostly fine on the TV! (Was this supposed to work??) I found I can mute the HDMI audio in alsamixer by setting S/PDIF off. No other control I tried has any effect on it. That is ok for me. Apart from the static in the laptop speakers, the primary annoying problem is that the HDMI audio has short gaps or pauses. I measured it by ear for a couple of minutes, and the gaps occur roughly 33 second intervals. The length of a gap is less than a second, maybe a half second. This bug is about the gaps. This is the same system as in my bug #60680 where we eventually got HDMI video output regression solved. You can find an old mmiotrace there, and VBIOS dump. -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
